It basically applies to anyone that was running their business for 3 years (NBO), so yeah 2006 is fine as you would have encountered the Recession up until 2009 for the study, while still falling into TEA classification. Feel free to fill it out , and thank you for asking.
To clear up for anyone unsure - Fill out the survey if you need the following criteria:
1. You are a business owner of UNDER 3 years
2. Your business was ran during these 3 years during some section of the recession (preferably 2007-2008)
Coincidentally, if you own a business of under 3 years you should fulfill both of these criteria anyway, this is just to stop me studying non entrepreneurial businesses that have passed a certain stage in their life.
